Default K70 RGB - Problems booting and Linux issues

I just got the K70 RGB keyboard and the M65 RGB mouse. I love them both! I plugged them while Windows was running and everything was fine. Then I tried to reboot to Linux.

To say it doesn't work would be an understatement. It just took me 1h15 to be able to boot to Linux (I use Grub) and have the keyboard actually work under Linux. Typically the keyboard works 1/4 times in BIOS / Grub and almost never under Linux.

I have installed the Unofficial Linux Driver and they do seem to work, as in I can change the lightning scheme and have the rainbow effect play.

The backspace key. Oh the backspace key. It just doesn't work. I have to arrow-back + del to delete typos.

When I boot in Windows, everything is fine. But I spend most of my time in Linux (Windows only for gaming) and this is getting very frustrating and I'd rather not return this keyboard as I love it when it does work.

The keyboard switch is set to "BIOS" as nothing else will ever work.

Some details on my system:

- Asus Hero Maximum VI with latest BIOS (1603, 2014/09/19)
- K70 RGB, updated to latest firmware (1.15)
- M65 RGB, updated to latest firmware (1.19)
- Windows 7 - 64 bits
- Linux Mint 17 - 64 bits
- Nothing else plugged in any USB port

Sorry, but if you use Linux more consistently than Windows, you're going to have a lot of issues if the Linux unofficial drivers didn't work optimally the first time.

You can either wait till they release Linux drivers themselves, or you can return the keyboard. They have more important issues to worry about on the Windows version themselves, so I wouldn't expect a Linux update for a while.

My understanding is that the BIOS mode on the switch is to make the keyboard look like any other USB keyboard, in which case it should work under Linux or any other OS. Even that isn't working.

I would talk to Corsair support then and see if you can RMA the keyboard, try to get a new one. You can try reinstalling the drivers and software for the keyboard as well if you think it's a software/firmware issue.

Nvidia 'gaming' graphics cards supports linux. Ati 'gaming' graphics cards supports linux. But a 'gaming' keyboard from Corsair can not?

My next peripheral purchase will not be from Corsair that's for sure.

It doesn't even work in the BIOS! It's basically not a compliant USB keyboard. I've been buying Corsair hardware for my past 3 PCs and came to really trust the quality of the brand.

This is a serious blow in the face. How can a keyboard that doesn't even work at boot time be shipped is beyond me. My biggest concern is that the issues are actually hardware issues. I say this because it shouldn't take months to fix firmware issues, unless they are seriously understaffed and/or lost critical engineers.

Trying to work around hardware issues with software takes a tremendous amount of time and you can't ever be sure you'll get there. This is what the situation with the K70 RGB sounds like to me.

My K65 RGB works fine in BIOS.

Your keyboard should work like any other USB keyboard in Linux.

I agree. That's why I started this thread.

An update: I have been experimenting with plugging the keyboard into the different ports on my PC. Trying to use any USB 3.0 port at the back will shutdown the computer (and the BIOS will complain about the power drain). Trying a USB 3.0 port at the front of my PC, I am able to boot roughly 50% of the time. Now the keyboard seems to work fine under both Windows and Linux.

I guess I can live with the inconvenience of resetting my computer 2-3 times each time I want to boot it.

So is that what the main issue is? Power drain? I'll see if I can find a powered USB hub and play with it.

We don't have the resources to fully support Linux so your results may vary. Our keyboard is USB compliant but we have found that its usually the motherboard that is not USB compliant.

If your keyboard doesn't enumerate properly in the BIOS, toggle the switch to BIOS and itll behave like a normal 104-key keyboard.

My keyboard's switch is on BIOS. If I try anything else, I can't get it to work at all. Even on the BIOS setting, it works every 2-3 attempts.

BTW I've tried 3 other keyboards and they all work properly. I've never had any USB problems with this computer. It is not impossible that there is some incompatibility caused by the Asus firmware, but I really doubt it. Either way, you would think that Corsair would have proper QA and test their keyboard with motherboards from major vendors (Asus in this case) and ensure the keyboard works with then. Following the spec is one thing, making your keyboard work with existing motherboards is another.
